Designing lightweight, high-assurance encryption for drone command and control (C2) links resistant to GPS spoofing and hijacking.
Unmanned Aerial Vehicles (UAVs) in defense and commercial critical infrastructure rely on wireless datalinks for flight guidance, mission telemetry, and payload control. Unauthenticated C2 links allow adversaries to inject false GPS coordinates, override autopilot commands, or capture high-definition reconnaissance video streams. RadioHSM secures these datalinks with sub-millisecond cryptographic authentication.
Autopilot feedback loops require command verification in less than 2 milliseconds to maintain stable flight dynamics. RadioHSM deploys specialized Galois/Counter Mode (GCM) coprocessors that authenticate and decrypt C2 packets on-the-fly, rejecting forged commands before they reach flight control microcontrollers.
For tactical reconnaissance drones operating behind enemy lines, weight and size are strictly limited. RadioHSM packages military-grade COMSEC into micro-modules weighing less than 15 grams, featuring automatic zeroization if the drone crashes or is recovered by unauthorized personnel.
